Granny sauce recipe?

Has anyone made a Jamaican "Granny sauce" from scratch? I plan on making some jerk soon, and can't imagine it without a granny sauce (kind of a cross between a barbecue and hot sauce), a la 3 Dives or Ossie's in Negril. I get the sense that there's probably a lot of different ingredients, most of which are probably secret, as only a good Granny would have, but any guidance would help.

Thanks!

If no one here has one, you might ask in the discussion groups at www.jamaicans.com ... they have a very active food section ("Ackee and Saltfish") and the recipe would be the real deal.

The grannies have to be super fresh, and you need a commercial food processor:)
